A typical case of me and my big mouth.
I figured that a basic analysis should reveal who wrote this:
http://news.ycombinator.com/item?id=1197027
Because of the size of the sample. So I wrote a bit of code to compare against other HN comments, and figured that that would turn up the user quickly.
But I was wrong, after two tries (Daniel Markham and John Graham-Cummings) I have to admit that my simple analysis has failed.
So, who will take up the challenge, can you identify this user somehow ?
